Embodiment Construction

[0021] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but may be limited within the scope of the appended claims and their equivalents. Modify within the complete scope of the object.

[0022] Typically, video media involves the display of a series of still images or frames in relatively rapid succession, allowing the viewer to perceive motion. Each frame may include multiple image elements or pixels, and each image element or pixel may represent a single reference point in the frame. During digital processing, each pixel may be assigned an integer value (eg, 0, 1...

Abstract

An apparatus used in video encoding comprising a processor configured to generate a prediction block for a current block, compute a difference between the current block and the prediction block to generate a residual block, wherein the residual block comprises a plurality of residual values, and if the plurality of residual values include at least one non-zero residual value comprising at least one sign and at least one residual level, perform entropy encoding on the at least one sign; and perform entropy encoding on the at least one residual level, wherein one non-residual value comprises one sign and one residual level.
